eclipse error with plugins after update

Question

I encountered a problem with

This version of the rendering library is more recent than your version of ADT plug-in.
Please update ADT plug-in

i tried this as learned from: Eclipse reports rendering library more recent than ADT plug-in

1. Click Help > Install New Software.
2. In the Work with field, enter: https://dl-ssl.google.com/android/eclipse/
3. Select Developer Tools / Android Development Tools.
4. Click Next and complete the wizard.

new problem:

An error has occurred. See error log for more details.java.lang.NullPointerException

i tried this on windows cmd ( again through some stackoverflow forums):

eclipse -clean -clearPersistedState

But i have not got any solution

This is new message:

An error has occurred. See error log for more details.com/android/utils/SparseArray

Error log has a lot of messages like:

Problems occurred when invoking code from plug-in: "org.eclipse.ui.workbench".

It shows whenever i try to open any layout xml file

after reverting ( as suggested by aumand) i am back on my first problem again with this msg on graphical layout of xml files ( i dont remember the exact words, but i think issue is something like >>>library i am using is 4.1.2 and the taget has loaded 4.4)

This version of the rendering library is more recent than your version of ADT plug-in. Please update ADT plug-in.

Plz help guyz..
